Letters Patent No. 108,130, dated October 11, 1870.

IMPROVEMENT IN CAR-ROOFS.

The Schedule referred to in these Letters Patent and making part of the same.

. Be it known that I, J OHN GARRY, of Cleveland, in the county of Ouyahoga and State of Ohio, have in vented certain new and useful Improvements in Car- Roofing, of which the following is a description.

Figure 1 is a top view of the car-roofing.

Figure 2, a view of the eaves.

Figures 3 and 4: are cud views.

Like letters of reference refer to like parts in the dificrent views. The nature of this invention relates to the manner of attaching sheet metal to car-roofs, so that said sheets shall be neatly and firmly connected thereto by means of certain flanges secured to the caves and ends of the root to which the edges of the sheets are locked, substantially as hereinafter described.

In the drawing, iig. 4.-

A represents the uncovered end of a car-roof, which is constructed of wood, in the ordinary way and of the usual shape, along the cares of which is secured a strip of metal, 13, fig.,2, having its upper edge tiirned outwardly at an angle forming a projectingitlange, O, fig. 4, which represents an end vicw of the strips rcl'erred to. 4

To the ends of the roof is also secured a similar strip, D, fig. 2, having a projecting flange in like mannor, to which, and to the strips along the eaves, the sheets of roofing E, fig. 1, are attached, as follows:

The several sheets to be laid upon' the roof are cut of a length a little more than that of the width-0f the roof, so that the ends of the roofing or sheets may extend beyond the edge of the projecting flange of the strips B.

The extending ends of the sheets are then turned down under the flange which it embraces, forming a lock-joint, as shown at a, fig. 4. It will be obvious that by this means the sheets are held closely down upon the roof without nails or other fast-enings in a strong and durable manner.

The sheets are secured in like manner to the ends of the roof, a strip, H, flg. 3, and flange, being nailed thereto, and the edge of the roofing turned under, the

flange embracing and forming a lock substantially the same Thesevcral sheets composing the roofing are connected to each other by a wide upturned flange, I, which are approximated and thus secured by a cap, J,placed on over the two upturned flanges, thereby locking them securely together, and excluding the rain and snow from between them.

The cap is secured to the flanges by eyelets b, inserted in holes punched through the cap and flanges, thereby riveting the flanges together in aneat, easy, and durable manner.

It will be observed that the flanges do not touch each other at their base orangle, but only at the top. The open space between the flanges allows the sheets to contract and expand, as they may be affected by the vicissitudes er the weather; hence no injurious strain can be exerted upon them to cause them to wrinkle and tear loose from their fastenings. Roofing thus attached to the roof can be removed therefrom entire by unlocking the lap from the flange of one end and then sliding the connected sheets endwise from the rooi',.or one section or more maybe removed singly, without disturbing the rest, by unlocking the lap ii'om the flange at the eaves, and removing the eyelets and cap. This being done, a sect-ion can be drawn transversely from the roofwithout injuring or disturbing those on either side.

Claim What I claim as my improvement, and desire to se cure by Letters Patent, is-

. The strip'B, provided with a flange, O, in combinaforth.
